[PsychoPy-users] get and save movie frame.

[John P. M. <jp...@uw...>]

I'm working to create .tif (or other) files that I can use in my own  
stimulus presentation software. Kids (5-6 YO) will be running this  
experiment, so i need to use my existing software to present the  
stimuli in  way I know will work, they will like, etc.

So I'd like to draw a grating and save it.

I've tried this:

# import things
from psychopy import visual, core

#define window
StimWin = visual.Window([200,200],monitor="testMonitor", units="deg")

#create a stimulus
Stim = visual.AlphaStim(win=SimWin, mask="gauss", size=4, pos=[0,0],  
sf=3.2)

#draw and update the window
Stim.draw()
StimWin.update()

#get and save
StimWin.getMovieFrame()
StimWin.saveMovieFrames('Stim1.tif')

and the file is blank. There must be something I am missing, but I  
can't see it. This is my first day with Python.

Thanks

John Paul
